Abstract

An unspecified-time airline ticket representing a purchased seat on a flight to be selected later, by the airlines, for a traveler-specified itinerary (e.g., NY to LA on March 3rd) is disclosed. Various methods and systems for matching an unspecified-time ticket with a flight are also disclosed. An exemplary method includes: (1) making available an unspecified-time ticket; (2) examining a plurality of flights which would fulfill the terms of the unspecified-time ticket to determine which flight to select; and (3) providing notification of the selected flight prior to departure. The disclosed embodiments provide travelers with reduced airfare in return for flight-time flexibility and, in turn, permits airlines to fill seats that would have otherwise gone unbooked. Because of the flexibilities required of the unspecified-time traveler, unspecified-time tickets are likely to attract leisure travelers unwilling to purchase tickets at the available published fares and, at the same time, are likely to “fence out” business travelers unwilling to risk losing a full day at either end of their trip. Moreover, the flexibilities required of the unspecified-time traveler need not be limited to a departure time; the flexibilities may also include the airline, the departing airport, the destination airport, or any other restriction that increases the flexibility afforded the airline in placing the traveler aboard a flight. The disclosed embodiments thus permit airlines to fill otherwise empty seats in a manner that stimulates latent and unfulfilled leisure travel demand while leaving their underlying fare structures intact.

TECHNICAL FIELD

This invention relates generally to a method and system for selling airline tickets.

BACKGROUND

Airlines have developed Revenue Management Systems (RMS) to optimize their revenue per flight. Revenue management can be separated into two distinct parts: pricing and seat inventory control. Pricing involves the establishment of fare classes and tariffs within those classes for each flight. Seat inventory control is the periodic adjustment of available seats for the various fare classes so as to optimize the passenger mix and thereby maximize the generated revenue. In particular, the objective is to fly an aircraft as full as possible without allowing the earlier-booking (discount-fare) leisure passengers to displace the later-booking (full-fare) business passengers.

Presently, tickets offered for sale by the airlines specify information including an itinerary (e.g., origin/destination locations and dates for travel) together with a flight number and a flight time. Once a passenger books a ticket, the airline is required to place the passenger aboard the flight indicated on the ticket rather than aboard a different flight for the same itinerary. In particular, once a ticket is booked, an airline has little or no flexibility in placing a discount-fare traveler aboard a later flight for the same itinerary in order to make available a seat for a full-fare business traveler. Even tour packages, once completed, do not provide the airlines with any flight-time flexibility.

Moreover, an airline's RMS typically knows well in advance, based on available historical data, that it will have empty seats on a given route (whether or not it will actually have empty seats on a given flight)—with more seats empty at certain times of the day or days of the week. However, the RMS cannot simply discount the published fares for those seats without either starting a fare war or compromising its underlying fare structure (i.e., without also having to reduce its full-fare prices for business travelers).

Placing a passenger on “standby” is one way for the airlines to fill empty seats. However, this practice is limited to instances where some oversight on the part of either the passenger or the airline has occurred and the passenger is now attempting to get aboard the next available flight. For example, the passenger may have arrived too late and missed his flight, or the passenger may have purchased a ticket at or near the time of the flight. However, the airlines generally do not use standby because of the high costs associated therewith. Moreover, standby is inconvenient for the passenger because there is no guarantee that he will get a seat on a flight departing that same day.

“Open” tickets are known in the field of airline travel where a passenger buys a ticket that can be used for any flight having an available seat. Open tickets, however, are utilized for flights selected by passengers. Open tickets thus do not solve the problem of how to fill available airline seats for the highest revenue and/or without undermining established fare structures.

Tour packages are known wherein a traveler initially receives a travel intinerary as part of a tour package purchase, and subsequently receives a ticket including notification of the flight number and time. In such tour packages, a tour operator is typically involved in purchasing groups of tickets. Again, while tour packages provide the operators with some flexibility in obtaining group rates for tickets, they do not solve the airline's problems of profitability filling empty seats.

Travel on military flights is typically according to orders, which gives the military operators absolute control over their flights. However, military flights are typically not paid for, and hence the military does not face the problem of revenue managing their seat allocation which is so problematic for commercial airlines.

Furthermore, although various “businesses” have existed and continue to exist which collect consumer demand for airline tickets and then manually interact with the airlines by way of phone or fax to purchase airline tickets for their clients at a reduced fare, these services are not truly automated in that they do not operate within the framework of the existing central reservation systems (CRSs), through which all airlines offer tickets for sale and all travel agents book such tickets.

As such, there is currently no way for the airlines to routinely fill excess capacity without undermining their underlying fare structures.

SUMMARY OF INVENTION

The problems identified above are solved and a technical advance is achieved in the art by providing, in accordance with the present invention, a system and method for providing a flexible airline ticket of unspecified departure/arrival time (i.e. an “unspecified-time ticket”). Such a ticket represents a purchased seat on a specific flight to be determined, by the airlines, for a traveler-specified itinerary (e.g., origin and destination locations together with the dates for travel).

A method according to one embodiment of the present invention includes: (1) creating a special fair listing for air travel to a specified destination from a specified origin on a specified day, the special fare listing excluding a specified departure time; (2) making available the special fare listing; (3) examining a plurality of flights which would fulfill the terms of a ticket corresponding to said special fare listing to determine which of the plurality of flights to select for the ticket, each of the plurality of flights including a specified departure time; (4) selecting one of the plurality of flights; and (5) providing notification of flight information, including the departure time, corresponding to the selected flight.

Thus, one embodiment of the present invention provides airlines with the flight-time flexibility necessary to fill potentially thousands of seats that would otherwise have remained empty each day. Airlines benefit from the additional flexibility of being able to balance intra-day demand by placing unspecified-time ticket holders aboard “low load” flights on a given day. Moreover, because of the flexibilities required of the unspecified-time traveler, unspecified-time tickets (and the reduced airfares associated therewith) are likely to attract leisure travelers unwilling to purchase tickets at the available published fares and, at the same time, are likely to “fence out” business travelers unwilling to risk losing the major part of the work day at either end of their trips due to the uncertainty of the exact times of the flight they might be placed on.

Moreover, the flexibilities required of the unspecified-time traveler need not be limited to a departure time. Rather, the flexibilities may include the airline, the departing airport, the destination airport, or any other restriction that increases the flexibility afforded the airline in placing the traveler aboard a flight. The present invention therefore permits airlines to fill otherwise empty seats in a manner that stimulates latent and unfulfilled leisure travel demand while leaving their underlying fare structures intact.

A system and method is also disclosed for providing a concealed carrier airline ticket, which permits an airline to conceal its identity when offering for sale through a CRS discounted tickets for flights on a specific route on a specific day.

A method according to this alternate embodiment includes: (1) creating an alias flight record based on an actual flight, the alias flight record excluding a carrier name; and (2) making available the alias flight record for electronic posting in a CRS.

Further aspects of the present invention will become apparent during the course of the following description and by reference to the attached drawings.

DETAILED DESCRIPTION

Referring now to the drawings,FIG. 1 illustrates one embodiment of the present invention.

As shown inFIG. 1, an airline's100 revenue management system (RMS)200 analyzes historical demand and pricing data for previous flights along a specific route (e.g., NY-LA) during the relevant time period to determine the number of actual flights to offer for a specific route on a specific day. Once this determination is made, theRMS200 instructs theairline scheduling system160 to create the actual flights. TheRMS200 also instructs theairline scheduling system160 to create a special fare listing for the same route on the same day. The term “special fare listing” as used herein is as a listing in an Airline Reservation System150 (ARS),CRS300 or the like for which atraveler105 may purchase an “unspecified-time” ticket. The “unspecified-time ”ticket, in accordance with the present invention, is an official airline ticket that represents a seat on an actual flight to be determined later, by theairline100, for a traveler-specified itinerary including the origin and destination locations together with the travel dates. Theairline scheduling system160 creates both the actual flights and the special fare listing, as instructed, and transmits the scheduling information to theARS150.

TheRMS200 also establishes a plurality of fare classes for the actual flights, utilizes historical data to forecast an expected demand over time (i.e., a demand curve) for tickets within a given fare class at a given price, and initially allocates and prices inventory sufficient to satisfy the expected demand. TheRMS200 transmits this inventory and pricing information to theARS150.

TheRMS200 also initially allocates inventory to the special fare listing corresponding to seats on the actual flights for the same route and day, which are forecasted to be empty at the time of departure. As is well-known in the art, theRMS200 can predict, based on available historical data, whether it will have empty seats on a given route. Moreover, the inventory initially allocated to the special fare listing is preferably offered at a lower fare/class than the available fare/class on the actual flights to encourage sales of unspecified-time tickets. In this regard, fare discounts associated with the special fare listing are preferably commensurate with the degree of flexibility afforded the airline in placing the traveler aboard an actual flight. For example, the wider the “window of departure” (e.g., 8 AM to 8 PM) associated with the special fare listing, the greater the discount. Conversely, the narrower the window, the smaller the discount.

For the actual flights, theRMS200 will monitor the actual demand within each fare class relative to the forecasted demand to dynamically reevaluate the inventory allocated to both the actual flights and the special fare listing. In accordance with the present invention, if the actual demand is less than the expected demand, theRMS200 will allocate additional inventory to the special fare listing at a lower fare/class than the currently available fare/class on the actual flights. Conversely, if the actual demand is greater than the expected demand, theRMS200 will reduce or eliminate inventory for the special fare listing. In either case, theRMS200 transmits inventory and pricing information for the special fare listing to theARS150 in the same manner as for the actual flights.

The inventory and pricing information for both the special fare listing and the actual flights is transmitted by theARS150 to theCRS300, either directly or, via the Airline Tariff Publishing Company (ATP Co.)115. As such, in the embodiment shown inFIG. 1, the unspecified-time tickets are made available to travelagents110 and theircustomers105 through theCRS300. The present invention thus minimizes investment in specialized systems since it is operable using a conventional CRS. Examples of such a CRS are known under the trade names Apollo, Sabre, System One and the like. Alternatively, thetraveler105 can purchase an unspecified-time ticket directly from theairline100. However, purchasing an unspecified-time ticket through a travel agent, rather than directly from the airline, has many advantages. For example, purchasing an unspecified-time ticket through a travel agent provides the traveler with flexibility in choosing an airline and thus, permits the traveler to “shop around” for the best fares on unspecified-time tickets.

As shown inFIG. 1, atraveler105 contacts histravel agent110 by way of phone, fax, online connection, e-mail or in-person, and provides thetravel agent110 with information regarding a specific itinerary. An itinerary includes the origin and destination locations together with the travel dates. Thetravel agent110 then logs into theCRS300 and obtains flight records for all flights that satisfy the requested itinerary. One of the flight records may be designated a “special fare listing” indicating that a traveler can purchase an unspecified-time ticket for a flight that satisfies the requested itinerary, although the actual flight itself and thus, the flight time, has not yet been determined by the airline. In any event, the unspecified-time ticket represents a commitment for carriage (i.e., an obligation by the airline to provide a seat on a flight) for the requested itinerary.

Thetravel agent110 would then discuss the benefits of booking an unspecified-time ticket for a special fare listing with thetraveler105. One example of such benefits includes reduced airfare as compared with conventional airline tickets. If instructed by thetraveler105 and, if there is available inventory for the special fare listing, thetravel agent110 will book the unspecified-time ticket through theCRS300 and create a passenger name record (PNR) number. Upon purchasing the unspecified-time ticket, thetraveler105 is provided with a special fare listing number and a notification date, by which date thetraveler105 will be provided with the actual flight number and a departure time.

TheCRS300 transmits in real-time, or on a periodic basis, as determined by theairline100, information regarding unspecified-time tickets booked for each airline to that airline'sARS150, which then forwards this information to theRMS200. For each booking, theRMS200 will obtain a listing of all actual flights that satisfy the travel parameters (i.e., O/D pair and date) of the unspecified-time ticket. TheRMS200 then analyzes the expected vs. the actual demand for each class on each actual flight and determines whether the actual demand is less than the expected demand for tickets for one or more of the actual flights. To narrow any discrepancy, theRMS200 instructs theARS150 to place a passenger from a special fare listing onto an actual flight. In the case where bookings are transmitted to theCRS300 in real-time, the travel agent notifies the passenger of the actual flight information in real-time (within seconds or minutes after transmission of the booking) or, alternatively, by a notification date, as will be discussed in detail hereinafter. Theairline100 prints the ticket for the actual flight with the actual flight number and the departure/arrival times and, transmits the ticket to thetraveler105, either directly or via thetravel agent110, depending upon whether thetraveler105 purchased the unspecified-time ticket through atravel agent110 or directly from theairline100.

Moreover, the flight record for a special fare listing, in addition to not specifying an actual flight number and departure time, may also not specify a ticket price. In this embodiment, theairline100 effectively solicitstravelers105 to submit bids for the unspecified-time tickets in the manner discussed in co-pending U.S. patent application Ser. No. 08/707,660, filed Sep. 4, 1996, and entitled, “Method and Apparatus for a Cryptographically Assisted Commercial Network System Designed to Facilitate Buyer-Driven Conditional Purchase Offers” and in a U.S. Patent Application entitled, “Conditional Purchase Offer Management” filed concurrently herewith, both of which are incorporated herein by reference. For example, a bid so submitted may specify that thetraveler105 wants to purchase an unspecified-time ticket for a specific itinerary, and that the traveler is willing to pay $375 for the ticket. Moreover, theairline100 may require that payment be guaranteed (e.g., by supplying a credit card number with a bid) upon acceptance by the airline.

Thetraveler105 could submit a bid to theairline100 in any number of ways. For example, a bid could be submitted via an online direct connection. Thetravel agent110 could also submit a bid on behalf of thetraveler105 using the e-mail capabilities of theCRS300. Alternatively, thetraveler105 could submit a bid via an Interactive Voice Response Unit (IVRU) (not shown) coupled to the airline's RMS120. In either case, an airline will be able to fill excess seating capacity without lowering its published fares and thus, without initiating a fare war.

TheRMS200 would render a decision to either accept or reject the bid based on the inventory and pricing guidelines in theRMS200. Thetraveler105 would be notified of the RMS's decision via the IVRU or a live operator. Also, if the bid were accepted by theRMS200, theRMS200 would then select an actual flight to place the unspecified-time traveler105 aboard, as described above, and thetraveler105 would be notified of the actual flight number and flight time accordingly.

Moreover, although the foregoing illustrates unspecified-time tickets offered by an individual airline, a “generic” unspecified-time ticket may also be offered, which, in addition to not specifying a flight number and flight time, would also not specify an airline. The “generic” unspecified-time ticket, like the airline-specific unspecified-time ticket, would be assigned a special fare listing number. As such, any airline offering actual flights that satisfy the travel parameters of the generic unspecified-time ticket and seeking to fill excess seating capacity could then query the CRS for bookings of generic unspecified-time tickets and place the traveler aboard one of its flights.

FIG. 2 depicts a block diagram of anexemplary RMS200 maintained byairline100. TheRMS200 performs all the operations of a conventional RMS and, performs additional operations in accordance with the present invention, as will be discussed in detail hereinafter. TheRMS200 includes aCPU205 together with associated memory (210,215) for: (1) creating both actual and special fare listings; (2) allocating inventory and fare/class to those flights; and (3) selecting an actual flight on which to place unspecified-time ticket holders, as will be discussed in detail hereinafter. TheCPU205 is coupled to an airline reservation system (ARS) via acommunications port220 for obtaining unspecified-time bookings from the ARS. As shown inFIG. 2, theCPU205 is also coupled to a data storage device225.

Data storage device225 includes a variety of databases including a forecasteddemand analysis database230, aflight schedule database240, aseat allocation database245, a pricing andrestrictions database250, and areservation database255.

Theflight schedule database240 of data storage device225 contains flight information including the origin and destination locations together with a departure date. The flight information also includes an actual flight number and the flight times, except in the case of a special fare listing. Theseat allocation database245 contains available inventory for each fare class on a given flight. The pricing andrestrictions database250 contains pricing information and related restrictions for each fare class on a given flight. Thereservation database255 contains each booking of a ticket for a given fare class on a given flight. Finally, the forecasteddemand analysis database230 contains information on each selling price for each fare class for a given flight, and the forecasted demand at each selling price, as established by theRMS200. Each of these databases will be discussed in detail hereinafter in conjunction withFIGS. 6-10.

FIG. 3 depicts a block diagram of an exemplary central server301 of acentral reservation system300. TheCRS300 performs all the operations of a conventional CRS and, performs additional operations in accordance with the present invention, as will be discussed in detail hereinafter. The server301 includes aCPU305 together with associated memory (310,315) for processing: (1) flight information received from the airlines; (2) itinerary inquiries regarding flight availability; and (3) ticket bookings. TheCPU305 is coupled to theCRS300 and theairlines100 via acommunications port320. TheCPU305 is also coupled to anelectronic mail processor322 for processing and storing (in storage device323) e-mail messages transmitted between theCPU305 and the various travel agents, airlines and the like.

As shown inFIG. 3, theCPU305 is further coupled to adata storage device325.Data storage device325 may include a variety of databases includingflight schedule database240,seat allocation database245, pricing andrestrictions database250, andreservation database255. These databases contain essentially the same information as the like-identified databases (240,245,250,255) in theRMS200.

FIG. 4 illustrates the manner in which theRMS200 utilizes the databases discussed in connection withFIG. 2 in implementing a pricing and inventory allocation process with respect to both actual flights and special fare listings. The format and content of the databases depicted inFIG. 4 are discussed in detail hereinafter in conjunction withFIGS. 6-10. It is to be noted that the pricing and inventory allocation process may be executed by theRMS200 initially when a flight is first added to the flight schedule and thereafter periodically to reallocate and price available inventory in response to demand and external events.

When either an actual flight or special fare listing is first added to the flight schedule of anairline100, a record of the flight with the appropriate itinerary information is created by theRMS200 in theflight schedule database240. In addition, theRMS200 will perform inventory allocation and pricing for both actual flights and special fare listings, to initially populate the fields of theseat allocation database245, pricing andrestrictions database250 and forecasted demand analysis database, as shown inFIG. 4.

Generally, during the initial pricing and allocation process for an actual flight, theRMS200 attempts to maximize revenue by first establishing a plurality of fare classes and thereafter allocating the number of seats and price assigned to each fare class. To this end, theRMS200 will utilize historical demand information stored in the forecasteddemand analysis database230 for prior periods, which essentially provides a demand curve for each selling price of a given fare class on each actual flight. For example, when allocating and pricing inventory for an actual flight, theRMS200 may analyze demand trends for similar flights from previous relevant time periods, in a known manner. Moreover, it is to be understood that conventional RMS systems typically respond to competitive forces and other external events, such as fare wars or increased demand due to a large event, such as the Olympics, as indicated by theexternal events database252, depicted inFIG. 4. Once calculated, the initial seat allocation and pricing information is stored in theseat allocation database245 and the pricing andrestrictions database250, respectively. The initial price for each fare class and the forecasted demand is also preferably stored in the forecasteddemand analysis database230.

In accordance with the present invention, theRMS200 also initially allocates inventory to the special fare listing corresponding to seats on the actual flights for the same route and day, which are forecasted to be empty at the time of departure. TheRMS200 can predict, based on available historical data, whether it will have empty seats on a given route (whether or not it will actually have empty seats on a given flight)—with more seats empty at certain times of the day or weeks of the year. Moreover, the inventory initially allocated to the special fare listing is offered at a lower fare/class than the currently available fare/class on the actual flights to encourage sales of unspecified-time tickets.

As shown inFIG. 4, the airline reservation system (ARS)150 and the central reservation system (CRS) will each access the establishedflight schedule database240,seat allocation database245, and pricing andrestrictions database250 to perform itinerary queries. In addition, as tickets are sold by theairline100, theARS150 orCRS300 will decrement the available inventory in theseat allocation database245. In this manner, theseat allocation database245 maintains an up-to-date representation of the available inventory for both actual flights and special fare listings.

For the actual flights, theRMS200 will continue to monitor theactual demand510 within each fare class relative to forecasteddemand520, as maintained in the forecasteddemand analysis database230 and illustrated inFIG. 5. TheRMS200 monitors current actual demand information by retrieving detailed inventory data from theseat allocation database245 or summary inventory data from the forecasteddemand analysis database230.

Anairline100 can correct for forecasting errors, or other competitive forces which have produced unanticipated excess capacity530 on a specific route by lowering its fare/class on the actual flights. In accordance with the present invention, theairline100 can also correct for such forecasting errors by increasing the inventory allocated to the special fare listing at a lower fare/class than the currently available fare/class on the actual flights. Due to the discouraged use of unspecified-time tickets by full-fare business travelers, anairline100 can sell such excess capacity at a discount, without undermining its existing published fare structure. Thus, in a preferred embodiment, theRMS200 will periodically execute the process discussed below in conjunction withFIGS. 13aand13b, to make unspecified-time tickets available for purchase by travelers.

FIG. 6 illustrates an exemplary forecasteddemand analysis database230, which records each selling price for each fare class for a given actual flight, and the forecasted demand at each selling price as established by theRMS200. As previously indicated, when a flight is first added to the flight schedule database of anairline100, a record of the initial price for each fare class and the forecasted demand is preferably established in the forecasteddemand analysis database230. In addition, new records are preferably created for each new selling price that is established for each fare class by theRMS200, as part of the dynamic inventory reallocation process.

The forecasteddemand analysis database230 includes a plurality of records, each associated with a different selling price for a given fare class on a given flight. For each flight number infield605, the forecasteddemand analysis database230 includes the departure date infield610, the origin and destination locations, infields615 and620 respectively, and the corresponding offered prices and fare classes, infields625 and630 respectively. Finally, the forecasteddemand analysis database230 preferably records the actual quantity of tickets sold by the airline at each offered price for each fare class infield640 and the corresponding expected quantity infield650. The actual quantity of tickets sold may be recorded in real-time as tickets are actually sold or by means of batch processing on a periodic basis.

FIG. 7 illustrates an exemplaryflight schedule database240 which preferably stores specific flight information for each origin and destination location pair (O&D Pair). Theflight schedule database240 maintains a plurality of records, each associated with a different flight. For each O&D pair listed in fields705-710, theflight schedule database240 includes the date of each flight infield715, as well as the departure and arrival times of the respective flight infields720 and725. The airline and flight number associated with each flight are preferably indicated, respectively infields730 and735, and any required connections are also indicated infield740.

FIG. 8 illustrates an exemplaryseat allocation database245 which maintains available inventory information for each fare class on a given flight offered by theairlines100, as allocated and updated by theRMS200. In addition, as inventory is sold by an airline, theARS150 will preferably decrement the available inventory recorded in theseat allocation database245. Theseat allocation database245 includes a plurality of records, each associated with a different flight. For each flight identified by a flight number infield805, theseat allocation database245 includes the departure date of the flight infield810 and the respective inventory available in each inventory class infields815 and820. In addition, theseat allocation database245 preferably includes an indication of the total number of seats booked on the flight infield825.

FIG. 9 illustrates an exemplary pricing andrestrictions database250 which maintains pricing information and related restrictions for each flight offered by anairline100, as established and updated by theRMS200. The pricing andrestrictions database250 includes a plurality of records, each associated with a different flight. For each flight identified by flight number infield905, the pricing andrestrictions database245 includes the date of the flight infield910 and the respective price and restrictions associated with each inventory class in fields915-930.

FIG. 10 illustrates anexemplary reservations database255 which maintains booking information for each flight offered by anairline100. Thereservations database255 includes a plurality of records, each associated with the booking of a ticket for a particular flight. Each record includes fields for a flight number infield1005, the O&D pair for the flight infield1010, the carrier infield1015, the class of ticket booked infield1020, the price of the ticket infield1025, and the passenger name record (PNR) number created upon booking infield1030.

FIGS. 11a-11care flow charts illustrating an exemplary process by which an airline's RMS creates both actual flights and special fare listings.

Instep1100, the airline'sRMS200 determines the number of actual flights to be offered for a specific route (e.g., NY-LA) on a specific day. In this regard, theRMS200 accesses the forecasteddemand analysis database230 and analyzes route-based information stored therein. Such information includes historical demand and pricing data for similar flights from previous relevant time periods.

Instep1110, theRMS200 transmits the O&D pair, the flight date, the number of flights to be offered, and the departure times to theairline scheduling system160. Thescheduling system160, instep1115, then creates a flight record for each flight. The flight record includes a flight number, the O&D pair, the departure date and time, an arrival date and time, an airline, and any restrictions.

TheRMS200, instep1120, also instructs theairline scheduling system160 to create a special fare listing for the same route on the same day. Instep1125, thescheduling system160 then creates a flight record for the special fare listing. The flight record will contain essentially the same information as the records created instep1115, except that the departure and arrival times infields720 and725 (SeeFIG. 7), respectively, will be unpopulated and, the flight number infield735 will be preceded by an “A” indicating a special fare listing, rather than an actual flight.

Referring toFIG. 11b, instep1130, theairline scheduling system160 enters the flight records (corresponding to both actual flights and special fare listings) into theARS150. In steps1135-1140, theARS150 stores the flight records in theflight schedule database240 and then transmits the records to theRMS200. Instep1145, theRMS200 also stores the flight records in theflight schedule database240. TheRMS200, instep1150, uses the information corresponding to each actual flight (i.e., flight number, O&D pair, and departure date) to generate a record for the actual flight in the forecasteddemand analysis database230.

Instep1155, the airline'sRMS200 forecasts an expected quantity of booked seats for each actual flight (i.e., the expected demand for the actual flight) and calculates a fare/class for the actual flight. In this regard, theRMS200 accesses the forecasteddemand analysis database230 and analyzes route-based information for each actual flight, including: (1) the total number of actual flights for the specified route on the specified day; (2) historical demand and pricing data from past flights for the specified route during the relevant time period; and (3) current pricing information (e.g., external events, which may affect pricing, such as the Olympics or a fare war). TheRMS200 then enters the expected quantity of booked seats for each actual flight together with the fare/class for the actual flight into the forecasteddemand analysis database230.

With reference toFIG. 11c, instep1160, theRMS200 allocates inventory for each class on each actual flight sufficient to satisfy the expected demand calculated instep1155. TheRMS200 then stores the inventory allocated instep1160 and the fare/class calculated instep1155, in theseat allocation database245 and the pricing andrestrictions database250, respectively. TheRMS200 also allocates inventory and pricing for the special fare listing. The allocation of inventory and pricing to the special fare listing is discussed in detail below in conjunction withFIG. 12.

Instep1165, theRMS200 transmits the inventory and fare/class for each flight (both the actual flights and the special fare listing) to theARS150. TheARS150 provides the scheduling, inventory and pricing information for each flight to the Airline Tariff Publishing Company (ATP Co.)115 instep1170. Thereafter, instep1175, the ATP Co.115 sells this information to the central reservation system (CRS)300. The CRS330 then creates records similar to those created by theRMS200 in theflight schedule database240,seat allocation database245, and pricing andrestrictions database250. Tickets are thus made available to travelagents110 and their customers through theCRS300 or, alternatively, totravelers105 directly via theARS150.

FIG. 12 is a flow chart illustrating an exemplary process by which an airline'sRMS200 initially allocates inventory to a special fare listing.

Instep1200, theRMS200 analyzes route-based information stored in the forecasteddemand analysis database230, theseat allocation database245 and pricing andrestrictions database250, including: (1) the total number-of actual flights for the specified route for the specified day; (2) the current fare/class on those flights; (3) the actual quantity of seats booked within each fare class on those flights relative to the expected quantity of seats booked; and (4) historical demand and pricing data for similar flights from previous relevant time periods.

In an effort to encourage sales, and thus, minimize the difference or gap (SeeFIG. 5) between the expected and actual quantity of tickets booked on the actual flights, theRMS200, instep1205, allocates inventory to the special fare listing at a lower fare/class than the currently available fare/class for the actual flights, based on the analysis instep1200. As determined by the airline, inventory may be allocated to the special fare listing either at the time actual flights are created or, some time thereafter, as a gap develops between the actual and the expected quantity of seats booked on the actual flights. Instep1210, theRMS200 generates and stores a record of the inventory allocated to the special fare listing and the associated fare/class in theseat allocation database245 and pricing andrestrictions database250, respectively.

It is to be understood that theRMS200 may also track the inventory allocated to the special fare listing and the associated fare/class together with the actual quantity of inventory booked at the fare/class in the forecasteddemand analysis database230. Over time, this will provide theRMS200 with a demand curve for each selling price at a given fare/class for the special fare listing. This information can then be used by theRMS200 instep1205, in addition to the information instep1200, to determine how much inventory to allocate to the special fare listing and, how much lower than the current fare/class on the actual flights to price each class of the special fare listing.

Instep1210, theRMS200 also transmits the inventory and fare/class information to theARS150. Instep1215, theARS150 stores the information locally and then transmits it to theCRS300, directly, or via the ATP Co.115. Instep1220, theCRS300 also stores the allocated inventory and fare/class in theseat allocation database245 and pricing andrestrictions database250, respectively.

It is to be understood that an airline may allocate inventory to a special fare listing which requires traveler concessions in addition to flight-time flexibility. Fare discounts would then be commensurate with the degree of flexibility afforded the airline in placing the traveler aboard an actual flight. For example, the airline may offer unspecified-time tickets for particular fare classes only, such as first class (K Class), coach (Y Class), one-stop, etc. The airline may also choose to limit unspecified-time tickets to “groups” of travelers (e.g., two or more, or any other number specified by the airline). Further examples of such concessions of flexibility include, but are not limited to, (1) the origin (if there is more than one airport in the area local to the traveler); (2) the destination (if there is more than one airport accessible for the traveler's ultimate destination); (3) the maximum travel time; (4) the number of stops; (5) the number of plane changes; and (6) whether or not non-jet aircraft (e.g., propeller planes) are involved.

FIGS. 13aand13bare flow charts illustrating an exemplary process by which an airline's RMS dynamically increases or decreases the allocation of inventory to a special fare listing.

Instep1300 ofFIG. 13a, theRMS200 accesses route-based information stored in the forecasteddemand analysis database230, including the actual quantity of seats booked within each fare class relative to the expected quantity of seats booked on a specific route on a specific day, to determine whether there is unanticipated excess capacity associated with the route on that day.

Instep1305, theRMS200 accesses theseat allocation database245 and retrieves the records corresponding to each actual flight for the specific route on the specific day. The RMS also retrieves the record corresponding to the special fare listing for the same route on the same day.

Instep1310, the RMS analyzes the records retrieved fromdatabase245 corresponding to each actual flight to determine whether each actual flight is completely booked (e.g., inFIG. 8, “Remaining Inventory”=0). If each flight is completely booked, theRMS200, instep1315, accessesdatabase245 and eliminates the remaining inventory allocated to the special fare listing (e.g., “Remaining Inventory”>0). For example, a special fare listing during Christmas week may not have any inventory allocated to it because of the heavy traffic that historically comes during the holiday seasons.

If each flight is not completely booked, theRMS200, instep1320, determines whether the “Total Inventory Booked” (SeeFIG. 8) for the special fare listing exceeds the remaining inventory for the actual flights. If it does, theRMS200, instep1315, accessesdatabase245 and eliminates the remaining inventory allocated to the special fare listing. However, if the total inventory booked for the special fare listing does not exceed the remaining inventory for the actual flights, the RMS proceeds to step1325 and determines whether the remaining inventory for the actual flights exceeds the remaining inventory for the special fare listing. If the remaining inventory for the actual flights does not exceed the remaining inventory for the special fare listing, instep1330, theRMS200 maintains the current remaining inventory for the special fare listing. If the remaining inventory for the actual flights exceeds the remaining inventory for the special fare listing, theRMS200, instep1335 ofFIG. 13b, increases the remaining inventory for the special fare listing at a fare/class below the currently available fare/class on the actual flights and updates theseat allocation database245 and pricing andrestrictions databases250, accordingly.

FIGS. 14aand14bare flow charts illustrating an exemplary process by which travelers book unspecified-time airline tickets.

Instep1400 ofFIG. 14a, atraveler105 contacts histravel agent110 and requests flight information for a specific itinerary. A specific itinerary necessarily includes the origin and destination locations together with the dates for travel, but may also include such information as travel times, airlines, etc. Instep1405, thetravel agent110 logs into aCRS300 and queries theCRS300 for all flights that meet the traveler's specifications. Instep1410, theCRS300 retrieves the relevant flight information from theflight schedule database240 and lists the information for thetravel agent110. Instep1415, thetravel agent110 reviews the information and determines whether there is a special fare listing for the requested itinerary. If there is, thetravel agent110 notifies thetraveler105 of the potential availability of an unspecified-time ticket for the requested itinerary and informs thetraveler105 that unspecified-time tickets are offered by the airlines at a lower fare/class than conventional airline tickets.

Instep1420, thetraveler105 instructs thetravel agent110 to purchase the unspecified-time ticket. Thetravel agent110, instep1425, obtains additional details regarding the unspecified-time ticket by retrieving inventory and pricing data for the special fare listing from theseat allocation database245 and pricing andrestrictions database250, respectively. If there is no inventory remaining for the special fare listing (step1430), thetravel agent115 will simply re-review the flight information listed by theCRS300 instep1410 for actual flight listings. Otherwise, thetravel agent110, instep1435 ofFIG. 14b, will book the unspecified-time ticket for thetraveler105 by creating a passenger name record and reserving a seat at the special fare listing in theCRS300.

Instep1440, theCRS300 stores the reservation in thereservation database255. Instep1445, theCRS300 modifies the record for the special fare listing in theseat allocation database245 by decrementing the “Remaining Inventory” by “1” and incrementing the “Total Inventory Booked” by “1”. Instep1446, theCRS300 receives the actual flight information fromRMS200, including a flight number and departure time, in real-time (e.g., minutes or even seconds after booking the unspecified-time ticket in step1435) and displays it for thetravel agent110. Instep1448, theCRS300 accesses theseat allocation database245 and modifies the record for the actual flight by incrementing the “Total Inventory Booked” by “1” and decrementing the “Total Seats Remaining” by “1”. TheCRS300 also modifies the record for the special fare listing by decrementing the “Total Inventory Booked” by “1”. Instep1450, thetraveler105 purchases the unspecified-time ticket and is immediately notified by thetravel agent110 of the actual flight information, including a flight number and departure time. Instep1455, the traveler receives an airline ticket for the actual flight.

In an alternate embodiment, theCRS300 does not receive the actual flight information in real-time. Thus, when thetraveler105 purchases the unspecified-time ticket instep1450, he receives only the flight number for the special fare listing and a notification date, by which date thetraveler105 will be provided with the actual flight number and a departure time. Instep1455, thetraveler105 then receives an airline ticket, including an actual flight number and departure time, either prior to, or by, the notification date.

FIGS. 15aand15bare flow charts illustrating an exemplary process by which an airline's RMS selects an actual flight on which to place an unspecified-time ticket holder. Instep1500, theCRS300 transmits the booking records stored in thereservation database255 for each airline to that airline'sARS150 on a real-time basis. TheARS150, instep1505, stores the information locally and then transmits it to theRMS200. Instep1510, theRMS200 accesses thereservation database255 and retrieves the booking records corresponding to a given special fare listing. Instep1515, theRMS200 accesses theflight schedule database240 and retrieves the records of all actual flights which satisfy the itinerary (i.e., O/D pair and date) of the special fare listing.

Instep1520, theRMS200 analyzes on a flight-by-flight basis information stored in the forecasteddemand analysis database230, including: (1) the total number of actual flights for the specified route for the specified day; (2) the current fare/class on each flight; and (3) the expected vs. the actual quantity of booked seats for each class on each actual flight.

Instep1525, theRMS200 determines whether the expected bookings on one or more of the actual flights exceeds the actual bookings for those flights. TheRMS200, instep1530 ofFIG. 15b, selects one of the actual flights as the flight on which to place the unspecified-time ticket holder. Instep1535, theRMS200 updates the forecasteddemand analysis database230 andseat allocation database245, accordingly. In particular, theRMS200 accesses the forecasteddemand analysis database230 and modifies the record for the actual flight by incrementing the “Actual Quantity Booked” by “1”. TheRMS200 also accesses theseat allocation database245 and modifies the record for: (1) the actual flight by incrementing the “Total Inventory Booked” by “1” and decrementing the “Total Seats Remaining” by “1”; and (2) the special fare listing by decrementing the “Total Inventory Booked” by “1”.

In an alternate embodiment, theRMS200 performssteps1515 through1535 for a predetermined number of bookings, even before receiving the booking records from theCRS300. Thereafter, theRMS200 can access this information upon receiving each booking record from theCRS300 to further expedite the placement of the unspecified-time ticket holder aboard an actual flight.

Instep1540, theRMS200 instructs theARS150 to place the passenger on the actual flight. TheARS150, instep1545, places the passenger on the actual flight and updates theseat allocation database245 in the same manner updated by theRMS200 instep1535. Instep1547, theARS150 transmits the actual flight information back to theCRS300. TheCRS300 receives the actual flight information in real-time (e.g., minutes or even seconds after it transmits the booking records to theARS150 in step1500). TheCRS300 also updates theseat allocation database245 in the same manner updated by theRMS200 instep1535.

Instep1550, theairline100 prints the ticket for the actual flight with the actual flight number and the departure/arrival times. Instep1555, theairline100 transmits the ticket to thetraveler105, either directly or via thetravel agent110.

Instep1560, the process of selecting an actual flight on which to place an unspecified-time ticket holder repeats for either another booking record corresponding to the same special fare listing (e.g., return to step1530) or a booking record corresponding to a different special fare listing (e.g., return to step1510).

In an alternate embodiment, the selection of an actual flight on which to place an unspecified-time ticket holder is not a real-time transaction. For example, theCRS300 may transmit the booking records stored in thereservation database255 to theARS150 on a periodic, rather than a real-time, basis. Similarly, theCRS300 and theARS150 may receive the actual flight information from theRMS200 hours, days or even weeks, after transmitting the booking records to theARS150.

With respect to this alternate embodiment, in the event that a traveler purchases an unspecified-time ticket close to the date of departure (e.g., a week or less), the travel agent or airline may have insufficient time to forward to the traveler a ticket with the actual flight data printed thereon. In that case, the airline can issue a ticket with the actual flight data except for the flight number and departure time. Once the airline has selected an actual flight for the traveler, the airline would provide the traveler directly, or through his travel agent, with a verification code together with the flight number and departure time. The traveler would then present both the initial ticket and the verification code when boarding the plane. Alternatively, the airline could forego issuing the initial ticket and the traveler would simply receive the verification code and use it to pick up the actual ticket at the airline's desk prior to departure. The traveler would then present the actual ticket when boarding. In addition, the airlines could use electronic ticketing (“E-Tickets”) to fulfill short term ticketing requirements.

An alternate embodiment of the present invention permits an airline to conceal its identity when offering for sale, via a CRS, discounted tickets for flights on a specified route (e.g., NY-LA) on a specified day. As such, this alternate embodiment permits an airline to fill empty seats on its flights without having to lower its own published air fares and initiating a fare war.

The airline conceals its identity from users of the CRS (e.g., travel agents or other airlines) by creating, and submitting to the CRS for posting, an alias flight record corresponding to each actual flight on a specified route on a specified day. The alias flight record is stored in the flight schedule database of the CRS (as well as the ARS and RMS) and contains all of the relevant flight information except for a carrier name, an actual flight number and precise departure/arrival times. The alias flight record is, as its name implies, an “alias” for the corresponding actual flight record, which is also stored in the flight schedule database, but for which discounted tickets are not offered.

Instead of an actual flight number and precise departure/arrival times, the alias flight record contains an alias flight number and time windows (e.g., 8:00 am to 11:00 am, “afternoon”, etc.), respectively. As such, users accessing the alias flight record are unable to ascertain the identity of the airline (either by way of an actual flight number or a precise departure/arrival times) offering the discounted tickets. The time windows provide customers with useful information regarding the departure/arrival times of the actual flight, but not enough information for a travel agent or another airline to identify the carrier. As with unspecified-time tickets, the time windows (coupled with the discounted fares) make these “concealed carrier” tickets particularly attractive to leisure travelers. It is to be understood that the alias flight record may also optionally include the model of the plane (e.g., Boeing 737), the number of seats on the plane, or any other means by which a travel agent querying the CRS could assure his customer that the customer, upon booking a concealed carrier ticket, will be flying on a reputable airline.

Moreover, although inaccessible to its users, the CRS contains an alias flight database, which it uses to correlate alias flight numbers with actual flights numbers and carriers (e.g., Alias Flight No. CC78969 corresponds to Continental Airlines Flight No. 36535). This correlation capability permits the CRS to relay bookings of tickets relating to alias flight records to the appropriate carrier and update inventory for the actual flights based on these bookings.

The alias flight records (and the related records in the forecasted demand analysis, seat allocation, pricing and restrictions, and reservation databases) in the RMS, ARS and CRS are created and updated in substantially the same manner as records for special fare listings relating to unspecified-time tickets. The primary difference is as follows: When a customer books an unspecified-time ticket corresponding to a special fare listing, the CRS is unaware of the actual flight upon which the customer will be placed and thus, the CRS must wait to receive this information from the airline before it can update inventory for both the special fare listing and the actual flight. In contrast, when a customer books a concealed carrier ticket corresponding to an alias flight record, the CRS knows the corresponding actual flight and thus, can update inventory immediately. Another difference is that the special fare listing for an unspecified-time ticket is created by the RMS on a “one-per-route” basis, whereas the alias flight record for the concealed carrier ticket is created on a “one-per-flight” basis.

Furthermore, the ticketing process for concealed carrier tickets is also similar to one of the ticketing processes discussed above with respect to unspecified-time tickets. Upon booking a concealed carrier ticket in the CRS, the travel agent issues and transmits to the customer a certified voucher containing the alias flight number and the PNR number created in the CRS. Once the airline receives the booking information from the CRS, it provides the travel agent with a predetermined notification date (e.g., 24 hours prior to departure), by which date the customer directly or, through the travel agent, will be provided with the carrier identity, actual flight number, and actual departure time. On the day of departure, the customer presents the certified voucher at the airline's flight desk, where the airline confirms the PNR number in the CRS and, if all is in order, presents the customer with a stub from the voucher for boarding the plane. Alternatively, as with unspecified-time tickets, the airline could use electronic ticketing to fulfill such short term ticketing requirements.

The many features and advantages of the present invention are apparent from the detailed specification, and thus, it is intended by the appended claims to cover all such features and advantages of the invention which fall within the true spirit and scope of the present invention.

Furthermore, since numerous modifications and variations will readily occur to those skilled in the art, it is not desired that the present invention be limited to the exact construction and operation illustrated and described herein, and accordingly, all suitable modifications and equivalents which may be resorted to are intended to fall within the scope of the claims.
